Earthwork Operations Risk Assessment

Product Overview

Identify and control organisational risks associated with Earthwork Operations at a management level, focusing on planning, governance, systems, and resourcing rather than task-by-task procedures. This Risk Assessment supports WHS Act compliance, demonstrates executive Due Diligence, and helps reduce organisational and operational liability across all earthmoving activities.

Risk Categories & Hazards Covered

This document assesses risks and outlines management controls for:

  • WHS Governance, Duties and Consultation: Assessment of officer due diligence, PCBU responsibilities, consultation arrangements with workers and contractors, and the integration of earthwork risks into the broader WHS management system.
  • Planning, Design and Geotechnical Risk Management: Management of design-phase decisions, geotechnical investigations, excavation classifications, and the review of drawings, reports and temporary works designs before earthworks commence.
  • Contractor and Supplier Management: Assessment of prequalification, selection and monitoring of earthwork contractors, subcontractors and material suppliers, including verification of insurances, licences and WHS capabilities.
  • Procurement and Management of Plant and Equipment: Protocols for selecting appropriate earthmoving plant, ensuring compliance with Australian Standards, guarding and safety features, and establishing systems for safe operation and decommissioning.
  • Maintenance, Inspection and Defect Management: Systems for scheduled servicing, pre-start checks, fault reporting, isolation and repair of earthmoving plant, attachments and support equipment used in earthworks.
  • Competency, Training and Supervision: Management of operator competency, verification of tickets and VOCs, task-specific training, supervision levels, and ongoing competency review for earthwork personnel.
  • Traffic, Interaction and Access Management: Development of traffic management plans, separation of mobile plant and pedestrians, spotter use, access/egress controls, and interaction with public roads and adjoining properties.
  • Ground Stability, Stockpile and Slope Management: Assessment of excavation stability, benching and batter design, stockpile placement, exclusion zones, and monitoring for signs of ground movement or collapse.
  • Manual Handling and Task Design for Manual Earthwork: Evaluation of manual excavation, shovelling, compacting and related tasks, including ergonomic design, load reduction, mechanical aids and job rotation strategies.
  • Environmental and Weather Risk Management: Management of dust, noise, vibration, erosion, sediment control, and the impact of rain, heat, wind and reduced visibility on the safety of earthwork operations.
  • Emergency Preparedness and Incident Management: Planning for trench collapse, plant incidents, service strikes and medical emergencies, including rescue arrangements, communication protocols and liaison with emergency services.
  • Documentation, Records and Continuous Improvement: Systems for recording inspections, maintenance, training, risk reviews, incident investigations and corrective actions to support ongoing improvement in earthwork safety performance.

Who is this for?

This Risk Assessment is designed for Business Owners, Construction Managers, Project Managers and Safety Leaders responsible for planning, approving and overseeing Earthwork Operations across civil, construction, mining and infrastructure projects.

Hazards & Risks Covered

Hazard Risk Description
1. WHS Governance, Duties and Consultation
  • • Lack of clear assignment of WHS duties for PCBUs, officers, supervisors and contractors under WHS Act 2011
  • • Inadequate consultation with workers and health and safety representatives about bulk earthworks, steep slopes and stockpile activities
  • • Poor integration of WHS obligations into contracts for principal contractor, subcontractors and plant hire providers
  • • Insufficient monitoring and review of WHS performance for earthwork operations (e.g. no WHS KPIs, no trend analysis on incidents)
  • • Failure to ensure due diligence by officers (e.g. directors, senior managers) in relation to high‑risk earthmoving activities
2. Planning, Design and Geotechnical Risk Management
  • • Inadequate geotechnical investigation of natural ground, cut faces and fill areas prior to earthworks on slopes and steep sites
  • • Poor design of ramps, batters, benches and access tracks leading to instability or plant rollover risks
  • • Insufficient assessment of existing ground conditions, underground services and previous land use before site clearance and levelling
  • • Lack of documented design criteria for formation of ramps and slopes, stockpile footprints and maximum allowable batter angles
  • • No systematic review of design changes (e.g. altered ramp gradients, modified stockpile locations) for WHS impacts
3. Contractor and Supplier Management
  • • Engagement of plant hire and earthmoving contractors without adequate WHS prequalification
  • • Inconsistent WHS standards and procedures across multiple contractors working on the same earthwork area
  • • Insufficient verification of contractor training, licences and experience in bulk earthworks, rock removal and steep site preparation
  • • Poor coordination of activities between different contractors leading to interaction risks near ramps, stockpiles and work fronts
  • • Lack of clarity over who controls specific earthwork locations, stockpiles and plant interfaces at any given time
4. Procurement and Management of Plant and Equipment
  • • Selection of earthmoving plant (excavators, dozers, graders, dump trucks, loaders) that is unsuitable for work on steep slopes or uneven terrain
  • • Plant lacking critical safety features (ROPS/FOPS, seatbelts, reversing alarms, cameras, load indicators) required for high‑risk terrains and stockpile work
  • • Use of non‑compliant attachments (rippers, buckets, rock breakers) without engineering verification
  • • Inadequate systems to ensure only authorised and competent operators use plant
  • • Poor control of hired‑in equipment that does not meet site WHS and maintenance standards
5. Maintenance, Inspection and Defect Management
  • • Inadequate preventive maintenance on critical plant used on ramps, slopes and stockpiles leading to mechanical failure
  • • Lack of systematic inspection of braking systems, steering, tyres, ROPS/FOPS and safety devices for machinery used on steep ground
  • • Poor management of defects reported during pre‑start checks, resulting in continued use of unsafe plant
  • • No scheduled inspection of earthworks features such as ramps, batters, benches and stockpiles for signs of instability or erosion
  • • Failure to monitor and maintain controls such as bunds, windrows and edge protection along ramps and drop‑offs
6. Competency, Training and Supervision
  • • Operators and spotters not adequately trained or experienced in bulk earthworks, earthworks on slope, steep site preparation and rock removal
  • • Limited understanding by supervisors of geotechnical risks, stockpile stability and safe ramp gradients
  • • Insufficient induction and task‑specific training for manual earthwork, rock removal by hand and handling of soil windrows
  • • Inadequate supervision of new or short‑term workers performing high‑risk tasks near ramps, stockpiles and excavation edges
  • • No ongoing verification that training translates into safe practices in the field
7. Traffic, Interaction and Access Management
  • • Uncontrolled interaction between heavy earthmoving plant and pedestrians during site clearance, grading, levelling and manual earthwork
  • • Poorly designed or undocumented haul routes, ramps and access tracks for plant travelling to and from stockpiles, windrows and work fronts
  • • Inadequate systems to manage reversing, blind spots and crossing points near ramps, steep slopes and stockpiles
  • • Lack of clear rules for exclusion zones around operating plant engaged in bulk earthworks and rock removal
  • • Insufficient controls for public interface where earthworks occur near property boundaries, roads or public access areas
8. Ground Stability, Stockpile and Slope Management
